Thermal time constant and thermal dissipation constant are reference values, which are values of elements and vary with connecting or fixing methods.
Thermal dissipation constant is approx. 4mW/ under the surface mounting condition. |
| *3 |
Specified current is a current value that is used at reliability test under the condition of self heat-generation that can be disregarded.
Oridinarily recommended measuring currents are 1mA for 100 and 0.1mA for 500. |

Precautions for Use |
| |
| |
When measuring current higher than rated current (100 : 1mA, 500 : 0.1mA) is used, calculate a rise in temperature by self-heating
and confirm the error range. |
